    Drop in's work good, you get a little extra power since it's not as restrictive as the paper filters. If you're not into changing out your air box it's the perfect upgrade. There are a few other companies out there that make cotton replacement filters for cars just can't think of the names off the top of my head right now.

    Not really a huge performance gain but the filter pays for itself by being reuseable.

    This is exactly what I was going to say. Good investment!

    any of the filters you buy will pretty much be the same. i have had a k&n in every vehicle i have ever owned. its really just personal preference. some other brands include green filters and aem makes one too. the biggest thing with them though is like the other guys said it just pays for itself over time. and everyone will make a fuss over the oil and how it messes up the maf and all that junk. as long as you follow the directions on the box and just not a complete moron you wont have any problems out of it.

    LAME mod. My dad had the k&n drop in in his previous truck, f250 and we found out that what they mean by a high flow drop in really means let's more dirt in and speeds up the flow of air also drop in. The guy at ez-lube told me that it would give me 30 hp
